Abstract

PURPOSE:To obtain the comfortable warming by setting a warmer to the 'strong' temperature with the first heater means and releasing the 'strong' temperature with the second control means and controlling the first and second heater means to the preset temperature with the first control means after lying in bed. CONSTITUTION:As soon as a power switch 7 is turned on, a transistor 15 is turned on, and the scale is set to 'strong'. When a human body lies in bed, the second sensor 3 is warmed, the impedance is lowered, a bed-in detecting circuit 11 is operated, the transistor is turned off, the second main control element 13 is turned on, and the sensor 3 serves as a thermal heater 3 to warm the shoulder section. The 'strong' temperature of the first thermal heater 2 is released. The 'strong' preset temperature is kept by the heater 2 and the heater 3 is not heated until a person lies in bed, and after the bed-in, the 'strong' temperature is released, the heater 3 is heated, and the heaters are controlled to the preset temperature, thus the comfortable warming can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device for sleeping such as an electric blanket.

Conventional technology When using a typical electric blanket, first turn the knob to "strong".
A good way to use the device is to pre-energize it for about an hour, then turn it down to your preferred usage level as soon as you go to bed. When using an electric blanket, such operations are always necessary, but sometimes there are problems such as forgetting to go to sleep with the pre-energization setting set to "strong" and waking up in the middle of the night due to the heat. Ta. In order to eliminate such problems, an electric blanket has been developed, as shown in FIG. 4, which, when the power switch is turned on, uses a timer circuit to maintain the bullet temperature for a certain period of time A, and then automatically returns to the set temperature.

Problems that the invention aims to solve However, with this type of electric blanket, time A is fixed, so when you go to bed at time B, for example, the timer circuit is still operating and the high setting continues. It's hot and you have to deactivate the timer circuit, and when you go to bed at point C, the knob automatically returns to the set temperature, so your cold body absorbs heat and the temperature drops, making you feel lukewarm. there were.

In view of the above-mentioned problems, the present invention relates to a heating device for sleeping that allows comfortable heating at all times.

Means for Solving the Problems In order to solve the above problems, the present invention provides a first heater means provided in a part of the main body outside the shoulder part, a setting means for setting the temperature of the main body, and a first heater means for setting the temperature of the main body. a strong setting means for making the temperature of the main body a strong temperature regardless of the set value of the setting means; a heat sensitive means provided at the shoulder portion of the main body; a second heater means also provided at the shoulder portion of the main body; and a first control means for controlling power supply to the first and second heater means so that the temperature of the main body becomes the temperature set by the setting means, and when the strong setting means is in operation, the second A second heater means that does not supply power to the second heater means and does not operate the strong setting means after the heat sensitive means detects a human body and supplies power to the second heater means.
This configuration includes a control means.

Effect: According to the above structure, the main body of the main body is kept at a strong temperature by the first heater means until the user enters the bed, and when the user enters the bed, the heat sensitive means detects the human body and the second control is activated. The high temperature is released by the means, and the first control means controls the first and second heater means to the temperature set by the setting means.

EXAMPLE An example of the present invention will be described below based on the drawings. 1st
The figure is a plan view of an electric blanket in an embodiment of the sleeping warming device of the present invention, showing a first thermal heater 2 wired to the blanket body 1 and a second thermal heater 3 for detecting when a human body enters the bed. There is a cord opening 4 at the terminal end of each thermal heater wire for connection to a controller 5. A second thermal heater 3 is wired to the shoulder portion of such a blanket body 1. FIG. 2 is a block diagram of the circuit configuration, and 6 is a power supply, and in series with the power supply 6 are a power switch 7, a first thermal heater 2, and a first main control element 8. In addition, in parallel to the power supply 6, a control circuit DC power supply circuit 9, a temperature detection circuit 10, a bed entry detection circuit 11,
A second thermal heater 3 and a second control element 13 are connected in series to the temperature control circuit 12 and power supply 6.The second thermal heater 3 detects the presence of a human body in bed and changes the temperature from the "strong" setting temperature to the knob setting temperature. After automatic return to normal state and detection of entering the bed, the second thermal heater 3 is energized by the second control element 13 and switched to keeping the shoulder area warm. The temperature detection circuit 1o includes a variable resistor 14 for temperature adjustment and a transistor 15 for setting the "strong j-th", and the transistor 15 is turned on at the same time as the power supply SW7 is turned on to set the "strong" eyesight. Also, when a human body enters the bed, the second thermal heater 3 is heated, and when the impedance shown in FIG. Element 13
is turned on, and the shoulder temperature rises to hp shown in FIG. Third
The figure shows the impedance characteristics of the sensor 3 wired to the shoulder part of the main body 1. It shows how the impedance decreases due to the influence of human body temperature upon entering the bed. When the temperature drops to /L/E, the detection circuit operates and the sensor 3 switches to a thermal heater to keep the shoulder area warm.

That is, according to this embodiment, the main body 1 is maintained at the "strong" set temperature by the first thermal heater 2 until the user goes to bed, and at this time, the comforter is generally not placed on the main body 1.
In addition, if heat is generated, the second thermal heater 3 installed at the shoulder of the main body 1, which only wastes heat indoors, does not generate heat, so the thermal efficiency is good, and the second thermal heater 3 does not generate heat, so it can be used to prevent human body. Entry into the bed can be detected reliably based on the temperature. Furthermore, when the user enters the bed, the strong temperature maintenance by the first thermal heater 2 is released, and the second thermal heater 3 also generates heat and is controlled to the set temperature, so that the shoulders and shoulders may be cold. , there are no problems with it being too hot.

Effects of the Invention As is clear from the above explanation, according to the sleeping heating device of the present invention, the heating device is preheated at a strong temperature by the first heater means until the user goes to bed, and after the user goes to bed. The heat sensitive means detects the entry of a human body into the bed, and the second control means releases the strong temperature maintenance and also supplies power to the second heater means,
The temperature set by the first control means is set at the set temperature.
Since the second heater means is controlled, the user does not get insufficient preheating or get too hot, making this a very user-friendly warming device for sleeping.
